Figure 4. Comparison of future and historic areal mean rainfall
accumulation for all 41 HPEs analyzed (a-b, Sect. 3.2), and the regional
maximal 10-min rain rates (i.e., along all the pixels in the region and
throughout timesteps) (c-d, Sect. 3.4). Scatter plots (a, c) compare the
historic (horizontal axis) and future (vertical axis) values. Violin
plots (b, d) show the distribution of historic (pale colors) and future
(bold colors) quantities for the different sub-regions (Fig. 1b). Each
dot along the violin represents a value of one HPE, white dots are
median values, and gray boxes are the inter quartile range. The change
between medians of historic and future events is marked with dashed
lines. Statistically significant differences between the paired-event
populations for each region (presented also as scatter plots in Fig. S3
and S7) are marked here with ** (see also Table 1).
Table 1: Changes in rainfall properties between future and
historic simulations. Bolded numbers are statistically significant (i.e.
on both paired t- and paired Wilcoxon signed-rank tests, Sect. 2.4).
Italics are significant on the paired t-test only. The upper value
represents the entire region and below are values for each sub-region
(land, sea, med=Mediterranean, and des=desert, Fig. 1b).
